MailBottle   11 #1 Posted May 1, 2019 Hi Having given up raising Koi carp a few years back in a small deep pond in the garden I decided to throw in a few Shubunkins, yellow and red goldfish and leave them to their own devices. Well after a shaky start about two years ago I started finding young black goldfish which as they grew I expected them to turn yellow or gold. No they said we are staying black so you can’t see us! When the Sun is out you can see about three generations of black goldfish sunbathing in the margins. I have a few other youngsters but they have gone white! The old koi filtration system takes care of the ammonia suggestion. Any ideas Share this post Link to post Share on other sites Share this content via...
